This paper describes a training analysis solution for the Army's Training Support System (TSS) that enables managers and analysts to conduct decision support activities through a combination of visualization and analysis techniques. The Army TSS is an emerging system of systems that, when fully mature, will provide the networked, integrated, interoperable training support and mission rehearsal capabilities necessary to enable an operationally relevant training environment for warfighters. In short, it is an integrated training support enterprise that is flexible and tailorable to meet dynamic training strategies. It is comprised of product lines, architectures and standards, and management, evaluation, and resource processes that enhance training effectiveness. The complexity of training support overwhelms traditional management and decision support tools such as spreadsheets and databases. Program managers and analysts need to look across TSS product lines to integrate enablers such as live, virtual, constructive (LVC) simulation architectures, ranges, and training ammunition to better synchronize training support. What is needed is a new capability that provides senior leaders and action officers a tool that enables them to iteratively observe, orient, decide and act based on a total vision of the TSS. The proposed solution is a visual-analytic model of the TSS that displays interdependencies among training enablers in ways not now possible. The paper will include a description of a prototype model that will focus on visualization and resource impact analysis of Urban Operations (UO) training. The model will provide a means to assess not just the immediate impact of the training solution, but also second and third order effects, as well as to identify redundancies, gaps, seams, and reuse opportunities. By applying visualization and analysis modeling techniques to map TSS enabling capabilities, leadership will have a more complete picture of the implications of current decisions on future training support.
